The Origin Story of YKK
‘YKK’ stands for ‘Yoshida Kōgyō Kabushikigaisha’, which translates in English to ‘Yoshida Manufacturing Corporation.’ The company was founded in 1934 by Tadao Yoshida in Tokyo, Japan. Yoshida, an ambitious and innovative entrepreneur, dreamed of creating a zipper manufacturing company that prioritized quality over quantity.
In its early years, YKK focused solely on zipper production but later diversified into other fastening products like snaps and buttons. Today, YKK produces approximately 7 billion zippers annually, accounting for nearly half of the world’s total zipper demand.
